The risks are clear to trainer Andrew Campbell as he prepares for a day of reckoning with his unbeaten sprinter Stick On.

But the rewards are also apparent as he ticks off the days until the gelding makes its Saturday city debut in the Coolalinga Handicap (1100m) at Flemington.

"I've been counting the sleeps," Campbell said.

"We've had this race in mind for a while and there doesn't seem to be any reason why he shouldn't run like we expect him to."

The only concerns Campbell has are a wet track and, to a lesser extent, the Flemington straight course.

"It's pretty difficult to get a wet track at Flemington these days so we're pretty happy he'll get decent ground," he said.

"And I can't see any reason why the straight track will worry him too much.

"Most of his work is done at the beach in a straight line, so he should be used to it."

Just in case, Campbell and his father and co-trainer Don have engaged Melbourne's leading jockey Glen Boss to handle the gelding.

"We've gone for the best jockey we can get, so that should take care of most things," he said.

Stick On has shown plenty of potential in his three wins from his only three starts, the latest a hollow all-the-way win at Geelong last month.

He's also endorsed the judgment of the father-and-son training team that paid $NZ28,000 for him two years ago.

Stick On has already returned twice as much as his owners spent on him and on Saturday is favourite to double that figure.

While the Flemington race will mark his Saturday debut in town, Stick On already has a city success to his name, having won over 1000m at Sandown on May 8.

Whatever the result on Saturday, the Campbells and the horse's other owners will stay in touch with reality and send Stick On for a spell with a view to bringing him back for a summer campaign.
